Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS-LR-PC(40) is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Receptacle, female socket configuration within the MSS series
• Impedance Rating: 50 ohms for RF signal integrity
• Mounting Configuration: Through-hole, right-angle orientation for PCB integration
• Contact & Shield Termination: Solder contact with crimp shield termination
• Frequency Performance: Maximum operating frequency of 500 MHz
• Environmental Compliance: RoHS compliance and MSL rating

The MSS-LR-PC-A(40) qualifies as a manufacturer-recommended substitute based on matching these core electrical and mechanical parameters while maintaining compatibility with existing PCB designs and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The MSS-LR-PC-A(40) is the manufacturer-recommended substitute for the MSS-LR-PC(40). Both connectors maintain identical electrical and mechanical specifications, ensuring direct compatibility in existing designs. The primary distinction is product status: the original MSS-LR-PC(40) is in Last Time Buy phase with limited inventory (771 pcs), while the MSS-LR-PC-A(40) is in Active production status with greater availability (1036 pcs). Both parts maintain RoHS compliance and equivalent environmental ratings. Selection should prioritize the MSS-LR-PC-A(40) for new designs and long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the MSS-LR-PC-A(40) be used as a direct replacement for the MSS-LR-PC(40)?

A: Yes. Both connectors share identical electrical specifications (50-ohm impedance, 500 MHz maximum frequency), mechanical configuration (through-hole, right-angle mounting), and termination methods (solder contact, crimp shield). PCB footprints and assembly processes remain unchanged.

Q: What is the difference between these two part numbers?

A: The MSS-LR-PC(40) is in Last Time Buy status with declining inventory. The MSS-LR-PC-A(40) is the active production equivalent with sustained availability. The "A" designation indicates the current production variant.

Q: Are there any compliance or environmental differences?

A: Both parts maintain RoHS compliance and MSL rating of 1 (Unlimited). Environmental operating ranges and material specifications are equivalent.

Q: Should I transition to the MSS-LR-PC-A(40) for new designs?

A: Yes. The active production status of the MSS-LR-PC-A(40) ensures long-term supply availability and design continuity. The Last Time Buy status of the original part indicates limited future procurement options.

Q: Are packaging specifications identical?

A: Both parts are supplied in bulk packaging suitable for manufacturing environments. Packaging specifications are equivalent for assembly and handling purposes.
